Distance and Rate question

It takes a freight train 2 hours longer to travel 300 miles than it takes an express train to travel 280 miles. The rate of the express train is 20 miles per hour greater than the rate of the freight train. Find the times and rates of both trains.

This question has been killing me. I cannot for the life of me figure it out. Please show your work so I can hopefully understand how you got to the final answer. Thank you sooooo much to who ever helps me out with this!!!
